Title: Spinning and winding of synthetic fiber yarn
Inventor: OGAWA TOSHIHARU
IPC: D01F6/62
Filed: 1984-12-27
Abstract: PURPOSE:To shorten the collection length of yarns, to eliminate large fluctuation of winding tension, and to enable sure winding of yarn, by carrying out the threading of a yarn at a low speed and increasing the winding speed while shifting the position of yarn collection according to the winding speed. CONSTITUTION:The yarn collection length L is varied by shifting the lubricant- application guide 3 vertically with the belt 16 driven by the rotation of the pulleys 13, 14, thereby shifting the collection guide 7. The pulse motor 15 is interlocked with the yarn-speed detector 18 via the arithmetic circuit 17, and is driven according to the yarn speed. The threading of the yarn is carried out by setting the winding speed at a low level and the yarn-collection position is shifted according to the increase in the winding speed to shorten the collection length of the yarn.

Abstract: PURPOSE:To obtain more satisfactory data for shading correction by using a roller for a reference member with prescribed density. CONSTITUTION:A reference roller 28 is fitted at the same height as an original loading surface and the initial position of an optics is lower than the reference roller 28. At such an initial position, a lamp is turned on by a CPU and a motor drive signal is switched from the drive of a lighting unit 24 to the rotation of the reference roller 28. When the data for shading correction are prepared before reading an original, the roller is read and the data over a wide range are obtained. By using these data, the calculation execution of the CPU is made correspondent. Thus, it is not necessary to execute a stop/restart operation in the case of calculation without enlarging a device even while comparatively widening the width of a white plate and of course, a large storing means is not required as well. Further, the more satisfactory data for shading correction is prepared.

Filed: 1988-11-01
Abstract: PURPOSE:To effectively use an address conversion buffer by holding a real address produced by a real address generating means via a register of a 2nd address conversion buffer at the first access when a converted pair of logical and real addresses to be obtained are not included in a 1st address conversion buffer. CONSTITUTION:When the corresponding real addresses are not included in the address conversion buffer circuits 100 and 200, a 2nd address conversion buffer circuit 400 is used. Then the real address is not included in the circuit 400 either. Thus a real address is obtained via a real address generating circuit 300, and the logical/real address conversion data is given to the circuit 100 or 200. When the same logical/real address conversion request is continuously received twice from an instruction or operand address conversion buffer circuit, an instruction for registering the data is given to an address conversion buffer. Then the data driven out of the address conversion buffer is registered in the circuit 400. As a result, the address conversion buffer can be effectively used.

Abstract: PURPOSE:To obtain a highly accurate remote controller with a simple constitution by transmitting the prescribed pulse to the receiving side from the transmitting side and controlling the transmission with the pulse satisfactory when the state where the pulse has the prescribed pulse width continues over a specified period. CONSTITUTION:Due to the pulse rise of a reception pulse (b) an on-delay timer 21 is activated, and its output (c) is turned on after a T1. Moreover a one shot circuit 22 is activated by the pulse rise of the output (c) to output the one shot pulse (d) in a T2. Said T1 and T2 set a lower limit and an upper one, respectively, in terms of testing the pulse width. By setting these limits, a signal for becoming 'H' only during a pulse width testing permissible period can be obtained in the output (d) of the one shot circuit 22, and a NAND circuit 26 takes the AND of the output (d) and the inversion output (e) of the reception pulse (b). If the inversion output (e) of the reception pulse (b) includes the pulse rise, a signal L with a satisfactory test can be obtained in the output (h) of the NAND circuit 26. With respect to the output signal (e) of an inversion circuit 23 a space pulse width test can be executed by a similar method.
